While Kate clearly doesn't need a nip or a tuck, she admits that the rampant plastic surgery speculation bugs her. "That's like asking someone if they see a therapist—and why?" she says, adding: "If someone wants to go get butt implants."

Another pet peeve? Those pesky paparazzi!

"I just look at the paparazzi and mentally cut their heads off," the 35-year-old admits. "The negatively is just so vast. Will everybody stop being so damned judgmental?"

The blonde beauty is no stranger to the negative side of fame. She posed with her mother for her first Instyle cover when she was just 17. "I joined the circus because I wanted to be part of the circus. I have a rebelliousness in me. I'm not interested in perfection—that's the whole point!"
